While the name "Deda" is synonymous with most road bike enthusiasts for it’s vast line-up of high quality stems, handlebars and related accouterments, few probably realize that the Italian brand also produces some very exquisite carbon framesets under it’s official namesake – Dedacacciai. While most of them ultimately get out sourced as private label pieces under the auspices of many high end brands, they are nevertheless available for public purchase. Just exactly how one goes about getting one – may prove to be the equivalent of trying to get Jimmy Hoffa to the telephone. But they do exist.
Here’s a glimpse at some of them:
The disk brake has introduced two main structural advanced concepts: first of all the increasing braking power with a great advantage for the safety of the cyclist, above all during wet conditions, and the aim of avoiding damages to the wheels especially for the carbon rims. Furthermore the traditional brake system could create an overheating of the carbon rims, particularly during long descents. That dynamic can quickly destroy the rim.
The R&D has equipped the RAN DB with a new front monocoque fork named K-23 with inner hydraulic cable passage in the left carbon blade. The K-23 is equipped with the "post mount" system tried and tested from the MTB sector. The crown of the fork has been reenforced to resist to the braking forces which concentrate at that main point. Tapered steering of 1"1/8 on the top and 1"1/4 bottom, which offers balance on every kind of asphalt, and superior handling precision.
The rear post mount has been positioned on the seat stays in order get a stable and safe braking.
The rear brake cable is positioned in the top tube through special hidden cable stops. That system reduces total weight and improves the look.
RAN is fully compatible with mechanical and electronic shifting systems (Shimano DI2, Ultegra and Campagnolo EPS, Athena and Sram), by running the cables inside the down tube and in the chain stays, via an internal bottom bracket passage. The refined attention to detail could be seen in the routing of the rear derailleur wire through the alloy rear dropout. The frame is also compatible with cable-operated shifting systems. That double compatibility is obtained by replacing small parts through the "cable stop" system described above. The mechanical groupset allows external wiring cables.
RAN is equipped with PF 30 (press fit 30) with bottom bracket length of 68 mm. Dedacciai offers BB30 and BSA adaptors as spare parts.
The PF30 (press Fit 30) standard has the classical bearings insertion BB30 (42 mm) in the Bottom bracket within pressure plastic caps. The central bottom bracket has an ID of 46 mm. The PF 30 adopts a bottom bracket with a bigger inner diameter compared to those available in the market. The versatility of the PF 30 allows the use of any type of bottom bracket design by using appropriate adaptors.

Super Scuro EVOLUZIONE
The Super Scuro Evoluzione frame is suitable for both electronic and mechanical devices and maintains its root of frame for longer and tougher road competitions, where it needs a high stiffness ratio during the winning sprint.
Super Scuro Evoluzione is the "alter ego" of Super Scuro RC with traditional and adjustable aero seat tube. The main difference is characterized by the aero integrated seat tube which represents for Dedacciai the ideal approach to competition in term of: rigidity, performance and the maximization of pedaling force. The carbon lay-out of the Super Scuro EVOLUZIONE is 3K.
Further evolution is represented by the front end which has been improved with the monocoque EDG fork. The EDG fork has been designed and engineered with the internal part of the blades directing the air flow onto the rim and in particular onto the brake track.
That particular function is important for carbon wheels where the overheating of the brake track decrease the braking power above all during a tough descent. The EDG fork with differentiate steering tube of 1"1/8 on the top and 1"1/2 in the bottom allows the best balance between rigidity and lightness.
In the engineering process special attention has been focused on the shape of the frame tubes with an aerofoil profile. In order to contribute to decrease the air resistance all the brake and gear shifting cables have internal routing through special hidden cable stops. They ensure the frame an unique appearance and at the same time a weight saving.
Super Scuro RC is fully compatible with mechanical and electronic shifting systems (Shimano DI2, Ultegra and Campagnolo EPS, Athena), by running the cables inside the down tube and in the chain stays, via an internal bottom bracket passage.

That double compatibility is obtained by replacing small parts through the "cable stop" system described above.
A saddle clamping system named King Pin is engineered to allow micro adjustment with an aerodynamic section clamp. That micro adjustment has been obtained through a hinge in the front part of the seat clamp and a support screw in the rear part, allowing a correct adjustment. Super Scuro RC is also compatible with our zero retraction seat clamp and the long version, which extends the seat tube by 20 mm.

Dedacciai and Deda Elementi engineers worked together to reduce and streamline the frontal area. The Flash II solution is a perfectly integrated combination of headset, stem, handlebar and aerobars.
Technical and research departments have focused on the link between headset and stem. The new CNC machined stem shows a revolutionary locking system including the expander inside: this made possible more clean and pure shapes. Clean shapes allow the reduction of turbulent air flow that creates aerodynamic resistance. The high level tech.
*stem creates with the horizontal top tube a smooth surface and a 6 mm horizontal regulation of the handlebar through metal spacers.

The frame developed for the enthusiast, Nerissimo eliminates the compromises of high modulus carbon fiber.
Nerissimo starts the 2014 season with the introduction of the double compatibility for electronic and mechanic devices thanks to the Dedaccai cable stop device. That compatibility is obtained by replacing "cable stops" which have been moulded into the monocoque. They ensure the frame an unique appearance and at the same time a weight saving.
Nerissimo, with its refined design, has a traditional shape which respects the biomechanical features with a sloping top tube that assures top comfort, especially over long distances. Nerissimo has been developed for the enthusiast cyclist who are looking for the best balance in quality and price.
Nerissimo has a great character and substance, characteristics that define the Dedacciai Strada brand. The frame can be used for long rides, yet is stable in a powerful sprint, responsive on a climb and precise in a fast descent.
The front end is precise thanks to the Stream full carbon fork with tapered 1"1/8 to 1"1/2 head tube, allowing firm, stable braking on entry into bends, and a confident feeling in the rhythm of changing direction.
The high modulus T700 carbon fiber monocoque with shaped main elements and unidirectional outer laminate are important technological assurances, as are the carbon dropouts, individual seat stays, and internal cable routing in the top tube. The external UD lay-out and the introduction of the new yellow sun version complete the Nerissimo frame which is now available in 4 colors: Yellow, matte Red, glossy White and Black.
